> DEFAULT keyword handling in MERGE UPDATE clause issues
> ------------------------------------------------------

> Key: HIVE-21172
> URL: https://issues.apache.org/jira/browse/HIVE-21172
> Project: Hive
> Issue Type: Sub-task
> Components: SQL, Transactions
> Affects Versions: 4.0.0
> Reporter: Eugene Koifman
> Assignee: Krisztian Kasa
> Priority: Major
> Labels: pull-request-available
> Time Spent: 1h 10m

> once HIVE-21159 lands, enable {{HiveConf.MERGE_SPLIT_UPDATE}} and run these
> tests.
> TestMiniLlapLocalCliDriver.testCliDriver[sqlmerge_stats]
> mvn test -Dtest=TestMiniLlapLocalCliDriver
> -Dqfile=insert_into_default_keyword.q
> Merge is rewritten as a multi-insert. When Update clause has DEFAULT, it's
> not properly replaced with a value in the muli-insert - it's treated as a
> literal
> {noformat}
> INSERT INTO `default`.`acidTable` -- update clause(insert part)
> SELECT `t`.`key`, `DEFAULT`, `t`.`value`
> WHERE `t`.`key` = `s`.`key` AND `s`.`key` > 3 AND NOT(`s`.`key` < 3)
> {noformat}
> See {{LOG.info("Going to reparse <" + originalQuery + "> as \n<" +
> rewrittenQueryStr.toString() + ">");}} in hive.log
> {{MergeSemanticAnalyzer.replaceDefaultKeywordForMerge()}} is only called in
> {{handleInsert}} but not {{handleUpdate()}}. Why does issue only show up with
> {{MERGE_SPLIT_UPDATE}}?
> Once this is fixed, HiveConf.MERGE_SPLIT_UPDATE should be true by default
